On the Revolution the needle is small and fits loose in the center hole of the A7. It only goes in about 1mm.
I squonk while doing a cold draw. Doing this twice fills the base of the A7.
Ok it all makes sense now
Sounds like you need a longer needle with a small U or L bend at the top....But good luck bending one with out kinking it.
Sounds like its working ok as is though, I just like to complicate things
